Energy Management Integrated WEB based monitoring solution for Solar PV applications Type Eos-Web Integrated modular local monitoring system for PV plants based on WEB access Up to 20 DIN modules configuration equivalent to 360mm width Eos-Web can manage on local bus up to 18 VMU units and up to 10 Eos-Array on RS485 bus. Eos-Web can manage in addition to VMU-C, WEB communication access master unit up to: - max 1 VMU-W unit - max 15 VMU-S units - max 1 VMU-P unit - max 3 VMU-O units - max 1 VMU-O.AT unit - max 1 VMU-1. Product Description Eos-Web is a combination of modules which performs the of a VMU-O module relay outputs alarm contacts and digital monitoring of a roof-top photovoltaic installation or a input status (e.g. to sense the tripping of the switch ground small to medium size plant. The core unit is VMU-C disconnector and the exhausting of the surge protection which in addition to the data-logging, web server functionality device). The VMU-W unit has the task to transmit, with wire- performs also the local bus management of VMU-S, VMU-P less modem technology, all the data when a wired LAN or both Measuring units, VMU-O I/O unit and VMU-W Internet access is not available.
